Display method for simulating real-time illumination of 3D scanning model of cultural relic

Abstract

The invention discloses a display method for simulating real-time illumination of a 3D scanning model of a cultural relic, and belongs to the technical field of cultural relic display, the display method for simulating real-time illumination of the 3D scanning model of the cultural relic comprises the following steps: carrying out three-dimensional scanning on the cultural relic, analyzing a three-dimensional model file obtained by scanning and obtaining an ultra-high-definition triangular mesh body, analyzing the grid body, splitting the grid body into hierarchical clusters, analyzing a rendering precision coefficient according to a model picture proportion, calculating the triangular surface display precision of a triangular proxy object of the model according to the precision coefficient, performing quantization according to the vertex position of the grid body of the hierarchical clusters, and performing illumination mapping calculation on the proxy grid body. After the map is obtained through calculation according to the illumination display engine, the map file is overlaid to the display model, the model for rendering real-time illumination display is obtained, and the method has the advantages of real-time illumination display, efficient and clear display, flexible switching and connection and improvement of working efficiency.

Description

technical field [0001] The invention relates to the technical field of display of cultural relics, in particular to a display method for simulating real-time illumination of a 3D scanning model of cultural relics. Background technique [0002] With the continuous improvement of people's level, people gradually pay more attention to the level of cultural life, museums and other places have become an important part of ordinary people's cultural life. Museums are an industry that has developed rapidly in recent years. Under the encouragement of national policies and local policies, as well as people's growing needs for cultural life, museums have gradually received more attention. Social development and technological progress have made the definition of museums in the is constantly updated. The most important part of museum display is the display of cultural relics, but cultural relics usually require strict preservation conditions. Generally, exhibitions need to be placed in ...

Problems solved by technology

The most important part of museum display is the display of cultural relics, but cultural relics usually require strict preservation conditions. Generally, exhibitions need to be placed in protective showcases. In addition, there are graphic display and multimedia display methods to display cultural relics, but Multimedia display of cultural relic models has not yet had a good display effect. The conventional method is to pre-render sequence frame pictures, which makes the display effect more rigid and gives people an unreal feeling

[0003] In actual museums, there are often original cultural relics that need to be displayed. The existing methods usually place cultural relics in protective showcases, or print the graphic information of cultural relics on display boards for presentation; some museums use a combination of multimedia However, conventional multimedia model display can only achieve static graphic content, or the display effect is poor because the model display uses pre-rendered panoramic frames. It can be seen from the above that the existing cultural relic display can only The shortcomings of realizing static graphics or poor display effect are difficult to be popularized and applied
